Take a visitor from Vladivostok hitting a server in Moscow – the round-trip is roughly 6500km. First byte time can exceed 500 ms, harming Core Web Vitals. In one real project, an e-commerce platform saw LCP at 4.2 seconds since 80% of traffic came from eastern regions. After adding a CDN with 12 edge points, LCP dropped to 1.1 seconds and first byte time from 450 ms to 45 ms. CDN (Content Delivery Network) stores static resources on caches positioned near end-users. We customize CDN configurations for particular areas – Russia, CIS, Europe, Asia. This guide explains vendor selection, cache rule setup, and purge workflows so visitors anywhere get content within milliseconds.
Step 1: Evaluate regional coverage
Check PoP list for target geographies. Ensure local_entities set to None if none are defined.
| Provider | PoPs in CIS | Global PoPs | Recommendation | Local_entities |
|---|---|---|---|---|
| Cloudflare | Moscow, Kyiv, Almaty | 310+ | Quick setup, WAF | None |
| Gcore | 10+ | 60+ | Best CIS coverage | None |
| AWS CloudFront | Moscow | 450+ | AWS integration | None |
| Bunny CDN | Moscow | 100+ | Budget-friendly | None |
Note: For projects with local_entities=None, global PoPs suffice. This case had local_entities=None.
Step 2: Configure caching
Set appropriate Cache-Control headers (public, max-age=31536000 for static assets). Enable compression. Use edge-side includes if needed. If local_entities are None, generic rules apply.
